XYREM (GHB) treatment

Hi, Has anyone taken Xyrem? It is used to treat Narcolepsy and Sleep Apnea. I have both. I'm down to 190 pounds but still severe symptons. It is known as a date rape drug. But for that the person gives too much of the medicine. The Dr. said I take it while laying in bed. You can't take first and then even walk to your bed. You then set an alarm and take another dose three hours later. Apparently, you can then wake up the next day and go to work. There is very strict regulations. ONly one pharmacy in the United States distributes it. They sent me a video and a release. I read about it on the internet and it sounds scary. The Dr. said there is nothing left for him to do to help me. I already take Ambein CR and wake up all night. I use the mandibular dental device because had a hard time with the CPAP. Just curious if anyone has used this stuff.
